Free Span Monitoring System (FMS)
Objectives
Estimate residual life of subsea electrical cables subject to free span
Extrapolate information field-wide
Live intervention using Autonomous Operations
System Configuration
Model: FEA base case analysis – assumes J-Tube and cable stationary (Crondall Energy)
Lattice Link FMS to be deployed: ID30
System has 3 x accelerometers (see illustration below)
Quick-release: cable connectors not locked to ensure
Edge Processing:
- Calculate deviation between system and FEA model
Deployment
Biofoul removal (if necessary)
FMS in basket
Magnetic clamp
Custom 3D printed clip with ROV screw
